How to Deploy WordPress with Docker and Docker Compose

WordPress is an open-source and popular content management system. However, installing and setting up WordPress on a new server is a very time-consuming process, especially if you need to do it again and again. In this case, you can use Docker and Docker compose to simplify your WordPress installation process using just a single command.

In this post, we will show you how to deploy WordPress with Docker and Docker Compose.


  • A fresh Ubuntu 20.04 server on the Atlantic.Net Cloud Platform
  • A root password configured on your server

Step 1 – Create Atlantic.Net Cloud Server

First, log in to your Atlantic.Net Cloud Server. Create a new server, choosing Ubuntu 20.04 as the operating system with at least 4GB RAM. Connect to your Cloud Server via SSH and log in using the credentials highlighted at the top of the page.

Once you are logged in to your Ubuntu 20.04 server, run the following command to update your base system with the latest available packages.

apt-get update -y

Step 2 – Install Docker and Docker Compose

First, you will need to install some required dependencies on your server. You can install them with the following command:

apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common -y

After installing all of them, add the Docker repository with the following command:

curl -fsSL | apt-key add -
add-apt-repository "deb [arch=amd64] $(lsb_release -cs) stable"

Once the repository is added, install Docker and Docker Compose with the following command:

apt-get install docker-ce docker-compose -y

After installing both packages, you can proceed to the next step.

Step 3 – Create a Docker-Compose YML File

Next, you will need to create a docker-compose.yml file to deploy the WordPress.

First, create a new directory named wordpress with the following command:

mkdir wordpress

Next, change the directory to wordpress and create a new docker-compose.yml file:

cd wordpress
nano docker-compose.yml

Add the following lines:

    image: wordpress
     - mariadb:mysql
     - WORDPRESS_DB_PASSWORD=secure-password
     - "your-server-ip:80:80"
     - ./html:/var/www/html
    image: mariadb
     - MYSQL_ROOT_PASSWORD=secure-password
     - MYSQL_DATABASE=wordpress
     - ./database:/var/lib/mysql

Save and close the file when you are finished.

Note: Replaced your-server-ip with your public IP.

The above file will download WordPress and MariaDB images from the Docker registry, create a database and set a password, link both containers, and expose the container on port 80.

Step 4 – Deploy WordPress

Now, change the directory to wordpress and launch the WordPress and MariaDB container with the following command:

docker-compose up -d

You should get the following output:

Status: Downloaded newer image for wordpress:latest
Creating wordpress_mariadb_1 ... done
Creating wordpress_wordpress_1 ... done

You can verify the downloaded images with the following command:

docker images


wordpress    latest    c2dd1984ad5b   3 days ago    551MB
mariadb      latest    eff629089685   13 days ago   408MB

You can also verify the running container with the following command:

docker-compose ps


        Name                       Command               State           Ports         
wordpress_mariadb_1 mysqld      Up      3306/tcp              
wordpress_wordpress_1 apach ...   Up>80/tcp

Step 5 – Access WordPress Installation Wizard

At this point, WordPress has been deployed and listening on port 80. You can access it using the URL http://your-server-ip. You should see the following page:
WordPress Installation Page
You can now follow the steps to complete the WordPress installation.

If you want to update both WordPress and MariaDB images, run the following command:

docker-compose pull

Now, push changes to your containers using the commands below.

docker-compose up -d

If you want to stop and remove all containers, run the following command:

docker-compose down
